Following the mass shootings at a Colorado movie theater and a Sikh temple in Wisconsin, guns and gun violence have become the focus of many New Jersey politicians.

PolitiFact New Jersey has tested several firearms-related claims on the Truth-O-Meter in the past few weeks.

We fact-checked U.S. Rep. Rush Holt's claim that "each day more than 80 Americans are killed by gunfire," as well as U.S. Sen. Frank Lautenberg's statement that "guns have murdered more Americans here at home in recent years than have died on the battlefields of Iraq and Afghanistan."

Find out how those statements -- and others -- have fared on the Truth-O-Meter in a recap at PolitiFactNJ.com and then join the conversation about it at NJ.com.
